The continued growth in the Default Free Routing Table (DFRT)
stresses the global routing system in a number of ways. One of the
most costly stresses is FIB size: ISPs often must upgrade router
hardware simply because the FIB has run out of space, and router
vendors must design routers that have adequate FIB.
FIB suppression is an approach to relieving stress on the FIB by NOT
loading selected RIB entries into the FIB. Simple Virtual
Aggregation (S-VA) is a simple form of Virtual Aggregation (VA) that
allows any and all edge routers to shrink their RIB and FIB
requirements substantially and therefore increase their useful
lifetime.
S-VA does not increase FIB requirements for core routers. S-VA is
extremely easy to configure considerably more so than the various
tricks done today to extend the life of edge routers. S-VA can be
deployed autonomously by an ISP (cooperation between ISPs is not
required), and can co-exist with legacy routers in the ISP.
